Abstract

The present invention relates to a dropper-type cosmetic container, which is configured so that in a process of releasing screw-coupling to a container main body by rotating a closing cap, by frictional force between an inner circumferential surface of a content inflow tube and an outer circumferential surface of a dropper pipe, the contents stored in the container main body pass through a content inflow hole forming a narrow channel, are dispersed, and are sucked into the dropper pipe, thereby allowing the contents to be drawn into the interior of the dropper pipe through a simple sucking structure to be used.

First claim

The invention claimed is:

1. A dropper-type cosmetic container, comprising:
a container main body in which contents are stored;
a content inflow part which is coupled to an upper portion of the container main body, is extended into the container main body, and is provided with a content inflow tube that is formed with a content inflow hole at a lower end of the content inflow tube and a content sucking pipe that is coupled to a lower portion of the content inflow tube and sucks the contents stored in the container main body;
a dropper part including a closing cap which is detachably coupled to the upper portion of the container main body, a dropper pipe which is inserted into the content inflow tube, sucks the contents flowing into the content inflow tube through the content sucking pipe, and is shaped like a pipe, and a compressing member which discharges the contents sucked into the dropper pipe by pressing by a user;
an upper portion of the closing cap surrounds and couples to the compressing member, and the compressing member surrounds and couples to an upper portion of the dropper pipe; and
wherein the compressing member seals against the content inflow part when the closing cap is coupled to the upper portion of the container main body.

2. The dropper-type cosmetic container of claim 1 , wherein one or more air movement holes are formed in the content inflow part.

3. The dropper-type cosmetic container of claim 1 , wherein the contents stored in the container main body pass through the content inflow hole, are dispersed, and are sucked into the dropper pipe by frictional force between an inner circumferential surface of the content inflow tube and an outer circumferential surface of the dropper pipe in a process of releasing the container main body by rotating the closing cap.

4. The dropper-type cosmetic container of claim 1 , wherein
the content inflow part further includes a sucking guide protrusion which is provided at an inner side of the content inflow tube, is in contact with an outer circumferential surface of the dropper pipe, and induces the contents to flow into the content inflow tube when the dropper pipe moves up, and
the contents stored in the container main body pass through the content inflow hole, are dispersed, and are sucked into the dropper pipe by frictional force between the sucking guide protrusion and the outer circumferential surface of the dropper pipe in a process of releasing the container main body by rotating the closing cap.

5. The dropper-type cosmetic container of claim 1 , wherein the content inflow part further includes an auxiliary sucking pipe which is coupled to an upper portion of an inner side of the content inflow tube, is in contact with an outer circumferential surface of the dropper pipe, and induces the contents to flow into the content inflow tube when the dropper pipe moves up, and
the contents stored in the container main body pass through the content inflow hole, are dispersed, and are sucked into the dropper pipe by frictional force between an inner circumferential surface of the auxiliary sucking pipe and the outer circumferential surface of the dropper pipe in a process of releasing the container main body by rotating the closing cap.

6. The dropper-type cosmetic container of claim 1 , wherein the content inflow part further includes an auxiliary sucking pipe which is integrally molded with an upper portion of an inner side of the content inflow tube by double injection, is in contact with an outer circumferential surface of the dropper pipe and induces the contents to flow into the content inflow tube when the dropper pipe moves up, and
the contents stored in the container main body pass through the content inflow hole, are dispersed, and are sucked into the dropper pipe by frictional force between an inner circumferential surface of the auxiliary sucking pipe and the outer circumferential surface of the dropper pipe in a process of releasing the container main body by rotating the closing cap.

7. The dropper-type cosmetic container of claim 1 , wherein the closing cap is screw-coupled to the container main body and is gripped by a hand of the user.

8. A dropper-type cosmetic container, comprising:
a container main body in which contents are stored;
a content inflow part which is coupled to an upper portion of the container main body, is extended into the container main body, and is provided with a content inflow tube that is formed with a content inflow hole at a lower end of the content inflow tube and a content sucking pipe that is coupled to a lower portion of the content inflow tube and sucks the contents stored in the container main body;
a dropper part including a closing cap which is detachably coupled to the upper portion of the container main body, a dropper pipe which is inserted into the content inflow tube, sucks the contents flowing into the content inflow tube through the content sucking pipe, and is shaped like a pipe, and a compressing member which discharges the contents sucked into the dropper pipe by pressing by a user;
an upper portion of the closing cap surrounds and couples to the compressing member, and a groove in the compressing member surrounds and couples to an upper portion of the dropper pipe; and
wherein the compressing member seals against the content inflow part when the closing cap is coupled to the upper portion of the container main body.
